渥太华哪里有买去除甲醛的活性炭颗粒?

我们讨论的是新房中甲醛污染的问题,以及用活性炭是否可以清除甲醛的问题。不要偏离这个主题,我说的是甲醛不能直接用到产品中了,但甲醛做为原料是不可能禁止的。甲醛作为原料生产粘合剂,但不能做为粘合剂的溶剂使用了。

我想说的是目前对甲醛的残留物标准,对大多数人以及现有经济基础上是合理的,目前没有经济适用的去除甲醛的方法,用活性炭是忽悠人的。

你看看你引用的哪些东西是针对我的论点的?

This was what you have said above:

现在这问题早就有定论了,所以生产中根本就不允许使用甲醛了。???:p

for now, either activated carbon filter or air purifier using chemi-sorb process can also deal with VOC and Formaldehyde but expensive....Health=money, all depends.

我不是已经解释了嘛?过去没有认识到甲醛的危害时,制造层板用的粘合剂中是含有大量的甲醛作为稀料,现在得用其它替代品,不许使用甲醛了。而甲醛作为化工原料,可生产许多产品,怎么可能禁止哪?

但制造粘合剂时由于反应不完全,肯定会有甲醛的残留,制造层板时经过干燥过程99%以上的有害物都挥发了,这时只要甲醛的残留符合行业标准,我们就称之为“没有”甲醛了。因为这是其它的有害物可能比甲醛多,该把目光盯在别处了。

室内的有害成分很多,不仅仅是新房,也不仅仅是甲醛。起码目前来说换气时最有效的方法。至于许多商人,利用人们对有害物的恐惧,夸大危害,制造一些忽悠人的产品来赚钱,不能人云亦云,该有自己的判断。

其实,我们俩的分歧是“活性炭和活性炭滤网”,您一看自己的观点不成,就赶紧就拐弯儿了。:D:D:D:D
 
初說沒有甲醛,又或已禁用,現又說carbon filter功效,,自圓其說。一直拐灣。甲醛釋放量低至0.04ppm已有問題,只不過法例寬鬆,未有嚴厲規管。美國現在才式規管甲醛含量,因商業利益比個人健康重要。
There are many different way in preparing activated charcoal. Each way will createe different pore size and total surface area. some may have effective surface area as much as 950平方米per gram!absorption can be as hing as 0.4g/g by weight.

The best purifier for now is by means of chemical absorption. it employs a strong oxidizing agent, potassium permanganate ,inpregnated alumina pallllets. it will oxidize 甲醛into water and carbon dioxide.

次選就要用activated charcoal. 只不過同一樣是operating cost high.

recently working on some green projects related with commerical building LEED reqt, studied this for a few month. some building other than using all clean green material, still have to run full ventilation with tens pounds of charcoal for a month before occupancy in order to@eliminate 甲醛 and VOCs.

哈哈,您连化学吸收都找出来了。看来有机化工博士专门研究和开发envirmentally and friendly有机溶剂的也不得不甘拜下风了?:p
